Man, I'm running to my local Michael's to see if they have a tube collection like that. I may have mentioned this before, but Michael's can't sell the left over "Picture Frame" cardboard they have, but they can give it to you. Walk in with a model and show them what you doing with it, it also helps if you have a couple tubes of glue and other doo-dads you are buying from them. They have so far given me almost 15 lbs. of the most amazing non-acidic cardboard, of all different colors and thicknesses that may take a coping saw to cut, FREE!! Michael's rules. I gave the Manager of that section a CD filled with models I had that were freely available, as he had no idea of this hobby whatsoever?
